Ma Capacitor Amafilimu okhala ndi Dielectric Zosiyanasiyana

Ma capacitors a filimunthawi zambiri amakhala ma cylindrical structure capacitors omwe amagwiritsa ntchito zitsulo (kapena zojambulazo zomwe zimapezedwa ndi pulasitiki yachitsulo) ngati mbale ya electrode, ndi filimu yapulasitiki ngati dielectric.

Ma capacitor amakanema amagawidwa m'mitundu yosiyanasiyana molingana ndi dielectric: ma polyester film capacitors ndi polypropylene film capacitors.

1. Polyester film capacitors

Polyester film capacitor (CL capacitor): Capacitor yomwe imagwiritsa ntchito filimu ya poliyesitala yazitsulo ngati dielectric ndi electrode, ndipo kunja kwake kumakutidwa kapena kusindikizidwa ndi epoxy resin.

Mawonekedwe: Kutentha kwapang'onopang'ono kogwiritsa ntchito, kukana kutentha kwabwino, kukhazikika kwa dielectric, kukhazikika kwamphamvu, mphamvu zamagetsi zamagetsi, kukana kwamphamvu kwambiri, kudzichiritsa bwino, komanso kuchuluka kwa voliyumu yayikulu.Imagwiritsidwa ntchito m'mabwalo a AC ndi DC pazida, mita ndi zida zapakhomo, komanso pamagawo ogawa pafupipafupi amagetsi.

2. Polypropylene film capacitors

Polypropylene film capacitor (CBB capacitor): Capacitor imagwiritsa ntchito filimu ya polypropylene ngati dielectric, aluminiyamu zojambulazo ngati maelekitirodi, ndipo imakutidwa kapena yokutidwa ndi epoxy resin.

Amadziwika ndi ntchito yabwino kwambiri yamagetsi, kudalirika kwabwino, kukana kutentha kwakukulu, kukula kochepa, kudzichiritsa bwino, komanso nthawi yayitali yogwira ntchito.Ndizoyenera ma TV, zowunikira makompyuta, zida zoyankhulirana, ndi ma siginecha ena a DC ndi VHF.Bypass, high frequency, AC, pulse, coupling circuit sefa, frequency modulation, DC blocking ndi zinthu zowongolera nthawi.

Mitundu yosiyanasiyana ya ma capacitor ili ndi mawonekedwe osiyanasiyana ndi zochitika zogwiritsira ntchito, choncho tiyenera kusamala posankha ma capacitors kuti tipewe mavuto.Sankhani wopanga wodalirika pogula ma capacitor a ceramic angapewe mavuto ambiri osafunikira.JYH HSU (kapena Dongguan Zhixu Electronics) sikuti ili ndi mitundu yonse ya ma capacitor a ceramic okhala ndi mtundu wotsimikizika, komanso imaperekanso kutsatsa kopanda nkhawa.Ngati mukuyang'ana zida zamagetsi, talandiridwa kuti mutilankhule.
